Description
Technical field
The present invention relates to a kind of monopole ultra-wideband antenna based on H-shaped groove, in the frequency range of 3.1GHz to 10.6GHz
By preferable working characteristics, its return loss has reached -51dB in minimum point, and in the range of 1.56GHz to 18GHz
Return loss is all below -10dB, and its working characteristics is preferable.
Ultra-wideband Communication Technology is widely used in the fields such as radar, positioning, electronic countermeasure and secret communication, for a long time by
Various countries are considered as sophisticated military technology and close protection, just gradually tend to civilian until in recent years.Ultra-wideband Communication Technology system it is excellent
Point can sum up as follows：1. highly concealed type.2. stronger multipath identification capability and the rate of information throughput higher.3. power system capacity is big.
4. penetration capacity is strong, it is easy to accomplish positioning is integrated with communication.5. it is low in energy consumption.
Ultra-wideband antenna is one of key components of super broad band radio communication system, and its design need to consider two aspect contents：
1. realize the ultra wideband transmissions characteristic from 3.1GHz to 10.6GHz (standing-wave ratio is less than 2)；2. consider and other narrow bandpass
The mutual interference problem of letter system, will possess the trap function of some narrowband slices while antenna carries out broadband communications.More than being based on
2 points of considerations, occur in that traditional method for designing with trap function ultra-wideband antenna, i.e., by circuit analyses such as effects, in day
Some slotted eyes (such as L-type groove, U-type groove) with specific function are increased on beta radiation unit, to reach required trap purpose.
Background technology
The original form of super-broadband tech [1-3] is impulse wireless communication, is originated from the forties in 20th century, and low side rate etc. of detecing is led to
Used in letter equipment.In recent years, with microelectronic component technology and technique raising, UWB technology starts to be applied to civilian neck
Domain.Ultra-wideband communications are a kind of without carrier wave, and are modulated by the pulse with very steep rising and falling time (generally,
Pulse width is between 0.20-1.5ns) a kind of communication, also referred to as impulse radio (Impulse Radio) time domains (Hime Domain)
Or carrierfree (Carrier Free) communication.It has the bandwidth of GHz magnitudes, and because its emitted energy is fairly small, it is thus possible to
A kind of brand-new voice and data communication mode are brought in the case of being not take up present crowded to capacity frequency resource.
After the frequency band of 3.1GHz to 10.6GHz is used by Federal Government developer, ultra-wideband antenna is just received
Greatly concern.Because the data processing speed being exceedingly fast and to eliminating the interference of part multipath effect, ultra-wideband antenna is considered as
One of outlet of following flirtatious communication system.Because composition of the indoor design of ultra-wideband antenna with conflict includes that impedance can not be perfect
Matching, and radiation the size of stability ultra-wideband antenna etc., so ultra-wideband antenna is also subject to during development
Certain limitation.Coplanar wave guide feedback antenna has lot of advantages such as bandwidth very wide, prepares that price is low is easy to and radio station
Frequency is compatible
Before in order to improve the bandwidth of paster antenna by many schemes, such as a relatively thick dielectric-slab is used,
Using the shunt resonators of low conducts constant, multiple parasitic pasters are stacked on main paster, or near the place of main paster
Place multiple pasters, U-shaped cutting, L-type probe, lossy medium etc..The radiation patch of printed antenna has many kinds
Form triangle, rectangle is oval, circular square, also a lot.

Specific embodiment
Because the monopole ultra-wideband antenna that the structure is based on H-shaped groove works in microwave frequency band, here will be by microwave transmission
Lineation opinion analyzes its radiation theory.Assuming that the radius of paster antenna triangle radiating element is half wavelength lambda/2, medium substrate
Thickness is L3.So, the Low ESR micro-strip that triangle radiating element, medium substrate and earth plate regard a length of λ/2 as can be passed
Defeated line, and form open circuit in radiating element edge.Again because dielectric substrate thickness is much smaller than wavelength X, thus electric field is along patch
The component of plate plane normal direction is substantially unchanged.In the case where only principal-mode excitation is considered, electromagenetic wave radiation can consider substantially
It is to be caused by the edge at radiating element open circuit position.Can by the electric field of open end be decomposed into along paster plane horizontal component and
Parallel to the vertical component of plane normal, wherein vertical component is cancelled out each other because of opposite in phase, therefore the horizontal component of electric field makes spoke
Penetrate the gap that unit open end is equivalent to cophase detector on infinity plane.So, radiating element to external radiation just it is equivalent into
The radiation in gap.
